Host-specificity and host-selection of gamasid mites (Acari: Gamasina)
Systematic and Applied Acarology, 1998Abstract Using methods to evaluate ecological niche breadth and overlap, I studied the host-specificity and the host-selection of 11 species of gamasid mites collected from 25 species of small mammals in western Yunnan, China, Levins' niche breadth was used for host-specificity, while Colwell-Futuyma's niche overlap and a fuzzy clustering analysis were

Reproductive systems of gamasid mites (Acari, Anactinotrichida) reconsidered
2002Gamasida (=Mesostigmata) are by far the most species rich and ecologically diverse anactinotrichids. Phylogenetic relationships between gamasid taxa are not solved and even highly controversial. In parallel with this discussion, which mainly refers to characters from external morphology, arguments from anatomy, fine structure, and behaviour in ...

[Distribution of hemorrhagic fever with renal syndrome virus in gamasid mites and chigger mites].
Zhonghua yu fang yi xue za zhi [Chinese journal of preventive medicine], 2003To study the distribution of hemorrhagic fever with renal syndrome virus (HFRSV) in mites.In situ reverse transcription-polymerase chain reaction (IS RT-PCR) was used for detecting the distribution of HFRSV in mites.HFRSV RNA was mainly located in ovary and mid-gut tissues of gamasid mites and chigger mites.

F‐Actin and Tubulin During Spermatogenesis in Gamasid Mites (Acari: Parasitina)
Acta Zoologica, 1993Abstract F‐actin and tubulin behaviour was investigated using fluorescence probes and electron microscopy in the course of spermatogenesis in two gamasid mites, Porrhostaspis lunulata Müller (Parasitidae) and Pergamasus truatellus Athias‐Henriot (Pergamasidae).

Infestation Rate of Gamasid Mites on Small Mammals in Northern Sweden
Insect Systematics & Evolution, 1972AbstractGamasid mites were collected from small mammals in the mountains of northernmost Sweden in autumn, winter/spring and summer. Laelaptidae and Liponyssidae were the most common families. Haemogamasidae comprised a rather small proportion of the material. Greatest infestation was recorded in early spring and in summer, when the number of mites per

[Gamasid mites (Gamasoidea) of the Taimyr Peninsula].
Parazitologiia, 19791591 specimen of small mammals, 467 nests of those, 250 birds and 38 nests had been investigated in 1972--1977. 19 182 specimens of gamasoid mites of 41 taxon had been found. Morphological and ecological adaptations of two mass species, Haemogamasus ambulans and Hinstionyssus isabellinus had been studied.

[Detection of hantaan virus from gamasid mite and chigger mite by molecular biological methods].
Zhonghua shi yan he lin chuang bing du xue za zhi = Zhonghua shiyan he linchuang bingduxue zazhi = Chinese journal of experimental and clinical virology, 2004To study the proliferation and location of hantaan virus (HV) in gamasid mites and chigger mites.HV RNA in gamasid mites and chigger mites were detected by reverse transcription, polymerase chain reaction (RT- PCR) and in situ hybridization.The smallest quantity of mite from which HV RNA could be detected was 5 mites group.

Host selection of ectoparasitic gamasid mites on Tylonycteris pachypus and T. robustula
Zoological Research, 2013Correlations of two species of gamasid mites (Macronyssus pararadovskyi and M. radovskyi) and their bat hosts (Tylonycteris pachypus and T. robustula) were studied by field surveys and indoor behavioral experiments. The wild data indicated that mite load was positively correlated with body condition index of female T.

Gamasid mites of small mammals in the semi-desert territories of Saratov Trans-Volga region
Entomological Review, 2017The paper contains the data on the species composition and comparative analysis of gamaside mites, parasitizing on small mammals in the semi-desert territories of Saratov trans-Volga region. On the basis of the results of investigations conducted in the Aleksandrovo-Gaisky District in 2008-2013, 18 species of gamaside mites (9 genusus, 5 families ...
